Description

Technical Field

[0001] This utility model relates to the technical field of connecting rod processing, specifically an automatic countersinking machine. Background Technology

[0002] In the field of door and window hardware manufacturing, hinge rods are a key component with high usage and precision requirements. To reliably rivet to the window or sash frame, hinge rods typically require countersunk holes machined into a single part. This allows for concealed installation of screws or rivets during assembly, ensuring a smooth appearance and avoiding interference. Currently, small and medium-sized door and window hardware enterprises in China still primarily rely on manual, single-machine, step-by-step processing for countersunk hole machining of these hinge rods.

[0003] Currently, when processing door and window hinge links, the process involves first machining oblique countersunk holes on a conventional drilling machine or bench drill using an oblique hole fixture, and then transferring the workpiece to another machine or changing the drill bit angle to machine flat countersunk holes. Hinges and links are small in size and have many holes, so manual visual positioning or simple positioning pins can lead to large errors. It is difficult to control the consistency of countersunk hole depth, angle, and hole spacing. Because the workpiece needs to be clamped and positioned multiple times, the processing efficiency is relatively low. Utility Model Content

Detailed Implementation

[0018] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0019] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0020] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0021] The present invention aims to provide an automatic countersinking machine for processing workpieces (whose shape and structure are similar to those of door and window hinge rods). In this embodiment, the workpiece is a door and window hinge rod. When loading, processing and unloading the door and window hinge rod, two are processed simultaneously.

[0022] Please see Figure 1 In this embodiment of the utility model, an automatic countersinking machine includes a workbench 1, and also includes a material storage mechanism 2, a feeding mechanism 3, a transfer mechanism 4, a feeding mechanism 5, an inclined hole drilling mechanism 7, a flat hole drilling mechanism 8, and a finished product unloading mechanism 6 disposed on the workbench 1.

[0023] The material storage mechanism 2 is equipped with two sets of material storage positions for placing door and window hinge links. The purpose of setting up two material storage positions is to ensure that after the door and window hinge links in one material storage position are removed, the other material storage position switches positions to supply materials. The staff replenishes materials to the material storage position where the door and window hinge links have been removed, ensuring the continuity of the processing process.

[0024] The feeding mechanism 3 is located on the side of the storage mechanism 2 and is used to grab two door and window hinge links from the storage mechanism 2 and send them to the transfer mechanism 4 to realize the automatic feeding of door and window hinge links.

[0025] The transfer mechanism 4 has three sets of transfer stations for receiving the door and window hinge links conveyed by the loading mechanism 3. When the moving mechanism 4 moves, only the distance between two sets of transfer stations moves. For ease of explanation, the three sets of transfer stations are defined as station A, station B, and station C. During loading, station A is located below the loading mechanism 3, while stations B and C are directly opposite the inclined hole drilling mechanism 7 and the horizontal hole drilling mechanism 8, respectively. When loading is completed at station A, and the inclined hole drilling mechanism 7 and the horizontal hole drilling mechanism 8 have finished processing the door and window hinge links on them, the two sets of clamping feeding positions on the feeding mechanism 5 clamp and deliver the door and window hinge links from the inclined hole drilling mechanism 7 and the horizontal hole drilling mechanism 8 to stations B and C. Station C is then moved by the transfer mechanism 4, which causes stations A and B to correspond to the inclined hole drilling mechanism 7 and the flat hole drilling mechanism 8. Station C moves to the finished product unloading mechanism 6. The feeding mechanism 5 clamps the unprocessed door and window hinge rods on station A to the inclined hole drilling mechanism 7 for inclined hole processing. At the same time, the feeding mechanism 5 clamps the door and window hinge rods with inclined holes already processed on station B to the flat hole drilling mechanism 8 for flat hole processing. The finished product unloading mechanism 6 removes the processed door and window hinge rods on station C and performs drilling depth detection. When the depth detection is qualified, it is sent out of the workbench 1. When the depth detection is unqualified, an alarm is triggered, and manual intervention is required to remove the unqualified door and window hinge rods.

[0026] In summary, this embodiment achieves automated countersinking of door and window hinge rods by orderly executing the feeding mechanism 3, the transfer mechanism 4, the feeding mechanism 5, the inclined hole drilling mechanism 7, the flat hole drilling mechanism 8, and the finished product unloading mechanism 6, thereby improving processing efficiency. At the same time, the step-by-step processing of door and window hinge rods by the inclined hole drilling mechanism 7 and the flat hole drilling mechanism 8 effectively improves processing accuracy.

[0027] Further, please refer to Figures 1-3 The material storage mechanism 2 includes: a material platform 201 slidably mounted on the workbench 1, two sets of material storage positions being arranged on the material platform 201, the material platform 201 being slidably connected to the workbench 1 through two sets of first sliding guide members 202; a first cylinder 203 mounted on the workbench 1 for driving the material platform 201 to move, thereby realizing the position switching of the two sets of material storage positions; and an upper lifting assembly including multiple top rods 206 that pass through the material platform 201 and can slide relative to the material platform 201, the top rods 206 being driven to move by a lifting drive member mounted at the bottom of the workbench 1, so as to maintain the position of the next door and window hinge link rising to the position of the previous door and window hinge link after one door and window hinge link is loaded.

[0028] In this embodiment, both sets of storage positions include two rows of feeding positions 204. The door and window hinge links are placed at the feeding positions 204. The feeding mechanism 3 simultaneously sends the two door and window hinge links located at the top of the two rows of feeding positions 204 to the transfer mechanism 4. Subsequently, the lifting drive drives multiple top rods 206 to move up by the thickness of one door and window hinge link, so that the next door and window hinge link rises to the position of the previous door and window hinge link, making it convenient for the feeding mechanism 3 to grab it. This realizes the continuous feeding of door and window hinge links and effectively improves the processing efficiency.

[0029] After all the door and window hinge links in one set of storage positions have been removed, the first cylinder 203 drives the material platform 201 to move, so that another set of storage positions moves to the current position. At this time, the feeding mechanism 3 can continue to grab door and window hinge links from the new storage positions for feeding without manual intervention, realizing automated switching of storage positions and further improving processing efficiency.

[0030] It should be noted that before the material platform 201 moves, the lifting drive needs to drive the top rod 206 downward so that the top rod 206 is removed from the position of penetrating the material platform 201. After the next set of storage positions moves to the current position, the lifting drive will drive the top rod 206 upward to penetrate the material platform 201 at the current storage position.

[0031] In one exemplary embodiment, the lifting drive includes: a mounting plate 207 fixed to the bottom of the workbench 1 and a first threaded connector 209 slidably mounted on the mounting plate 207, wherein a lifting frame 208 for connecting a top rod 206 is fixed on the first threaded connector 209; and a first threaded rod 210 rotatably mounted on the mounting plate 207 and driven to rotate by a first motor 211 mounted on the mounting plate 207, wherein the first threaded rod 210 passes through the first threaded connector 209 and is threadedly connected to the first threaded connector 209.

[0032] The first motor 211 drives the first threaded rod 210 to rotate, thereby driving the first threaded connector 209 to move vertically, so as to drive the top rod 206 to move through the lifting frame 208.

[0033] For example, in one embodiment, the feeding position 204 includes: multiple first fixing rods 2041 and second fixing rods 2042 fixed on the material platform 201, with a placement gap formed between the first fixing rods 2041 and the second fixing rods 2042 for placing the door and window hinge connecting rods; the ends of the first fixing rods 2041 and the second fixing rods 2042 away from the material platform 201 are formed with tapered portions to facilitate the placement of the door and window hinge connecting rods into the placement gap; and a positioning rod 205 fixed on the material platform 201, which passes through a through hole on the door and window hinge connecting rod to restrict the door and window hinge connecting rod, ensuring that the door and window hinge connecting rods are all in the same position when they are grabbed by the feeding mechanism 3, preventing misalignment from affecting subsequent feeding.

[0034] Please see Figure 1 and Figure 4 The feeding mechanism 3 and the finished product unloading mechanism 6 have the same structure, both including: a support plate 301, which is fixed to the workbench 1 by at least two first uprights 302; a connecting plate 306, on which a second mounting plate 309 is vertically fixed, and on which a plurality of negative pressure suction nozzles 310 are mounted; and a first two-dimensional moving drive unit, which is mounted on the support plate 301 and is used to drive the connecting plate 306 to move in the horizontal and vertical directions.

[0035] For example, the first two-dimensional motion drive unit includes a first mounting plate 305 slidably mounted on the support plate 301 via a second sliding guide 304. The first mounting plate 305 is driven to move by a second cylinder 303 mounted on the support plate 301, and the movement state of the first mounting plate 305 is horizontal. The connecting plate 306 slides vertically on the first mounting plate 305 via a third sliding guide 308 and is driven to move by a third cylinder 307 mounted on the first mounting plate 305.

[0036] In this embodiment, the second cylinder 303 drives the first mounting plate 305 and the entire assembly mounted on the first mounting plate 305 to move above the storage position. Then, the third cylinder 307 drives the connecting plate 306 to move downward so that the negative pressure suction nozzle 310 abuts against and attracts the door and window hinge link. Then, the third cylinder 307 drives the connecting plate 306 and the negative pressure suction nozzle 310 to move upward. The second cylinder 303 drives the negative pressure suction nozzle 310 and the door and window hinge link to move above station A. The third cylinder 307 drives the connecting plate 306 and the negative pressure suction nozzle 310 to move downward again to send the door and window hinge link to station A, thereby realizing the loading action. During this process, the negative pressure suction nozzle 310 tightly adheres to the door and window hinge link by generating negative pressure, ensuring that the door and window hinge link will not fall off during the movement.

[0037] It should be noted that the multiple negative pressure suction nozzles 310 are arranged in two rows, which are used to simultaneously suction and feed the two door and window hinge links.

[0038] Please see Figure 1 and Figure 5 The transfer mechanism 4 includes: a transfer platform 401 slidably mounted on the workbench 1 and driven to move by a fourth cylinder 403 mounted on the workbench 1; the transfer platform 401 is slidably connected to the workstation 1 via a fourth sliding guide 402; the transfer platform 401 is provided with three sets of receiving units, which correspond to workstations A, B, and C respectively; wherein: the receiving unit includes: a placement platform 405, which is fixed to the transfer platform 401 by a second upright 404; a placement position for placing the door and window hinge link is formed on the placement platform 405 by a plurality of symmetrically arranged limiting blocks 406; and a positioning protrusion 407, which is mounted on the placement platform 405; when the door and window hinge link is placed in the placement position, the positioning protrusion 407 penetrates the through hole on the door and window hinge link.

[0039] It should be noted that two placement positions are formed on a placement platform 405, and the door and window hinge connecting rods conveyed by the feeding mechanism 3 are positioned by the positioning protrusion 407 and multiple limiting blocks 406.

[0040] Please see Figure 1 , Figure 6 and Figure 7 The feeding mechanism 5 includes: a first mounting frame 501 fixed on the workbench 1; a sliding plate 508 on which two sets of clamping units are symmetrically mounted; and a second two-dimensional moving drive unit disposed on the first mounting frame 501, used to drive the sliding plate 508 to move in the horizontal and vertical directions, so as to clamp the workpiece to be processed from the transfer mechanism 4 to the inclined hole drilling mechanism 7 and the flat hole drilling mechanism 8 or from the inclined hole drilling mechanism 7 and the flat hole drilling mechanism 8 to the transfer mechanism 4 through the clamping units.

[0041] The clamping unit includes a rotary cylinder 514 mounted on the sliding plate 508. The output shaft of the rotary cylinder 514 passes through the sliding plate 508 and is fixed with a pneumatic gripper 510.

[0042] Preferably, the clamping unit includes two rotary cylinders 514 and two pneumatic grippers 510. The pneumatic grippers 510 clamp the door and window hinge link. The rotary cylinders 514 can drive the pneumatic grippers 510 to rotate. When double-sided processing of the door and window hinge link is required, the door and window hinge link can be flipped through the driving action of the rotary cylinders 514. Of course, when only single-sided processing is required, the rotary cylinders 514 remain in a self-locking state.

[0043] In one exemplary embodiment, the second two-dimensional motion drive unit includes a sliding support plate 503 slidably mounted on the first mounting frame 501 via a fifth sliding guide 502 and a fixed upright plate 504 fixed on the sliding support plate 503. A vertical drive member for driving the sliding plate 508 to move vertically is mounted on the fixed upright plate 504. The unit also includes a rack plate 511 fixed on the first mounting frame 501 and a gear 513 rotatably mounted on the sliding support plate 503 and driven to rotate by a third motor 512. The gear 513 meshes with the rack plate 511.

[0044] In this embodiment, the gear 513 is driven to rotate by the third motor 512. When the gear 513 rotates, it works in conjunction with the rack plate 511 to move the sliding support plate 503 and the entire assembly mounted on it toward or away from the inclined hole drilling mechanism 7 and the flat hole drilling mechanism 8, so as to realize the clamping unit's clamping drive (horizontal direction) on the door and window hinge linkage.

[0045] The vertical drive component includes a second threaded rod 507 rotatably mounted on the fixed plate 504 and a second threaded connector 509 fixed on the sliding plate 508 and threadedly connected to the second threaded rod 507. The second threaded rod 507 is driven to rotate by a second motor 506 mounted on the fixed plate 504.

[0046] It should be noted that the sliding plate 508 is slidably connected to the fixed plate 504 via the sixth guide sliding member 505.

[0047] The second threaded rod 507 is driven to rotate by the second motor 506. When the second threaded rod 507 rotates, it works in conjunction with the sixth guide sliding member 505 to drive the second threaded connector 509, the sliding plate 508 and the clamping unit to move vertically, so that the clamping unit can clamp and drive the door and window hinge linkage (vertical direction).

[0048] Please see Figure 1 and Figure 8The inclined hole drilling mechanism 7 includes: a second mounting frame 701 mounted on the worktable 1; a sliding receiving frame 703 slidably mounted on the second mounting frame 701 and driven by a fifth cylinder 702 to move vertically, wherein a drilling unit is mounted on the sliding receiving frame 703, and the sliding receiving frame 703 is slidably connected to the second mounting frame 701 via a seventh sliding guide 704; and a receiving platform 712 fixed on the second mounting frame 701 and corresponding to the drilling unit, wherein a positioning member 713 is mounted on the receiving platform 712, wherein the positioning member 713 penetrates the receiving platform 712. 2. It is slidably connected to the receiving platform 712. The positioning member 713 is moved by the telescopic drive member (cylinder or electric telescopic rod) installed on the second mounting bracket 701. So after the door and window hinge link is placed on the receiving platform 712, the positioning member 713 moves up and passes through the through hole on the door and window hinge link to realize the positioning of the door and window hinge link. The clamping unit clamps the door and window hinge link onto the receiving platform 712. The positioning member 713 moves up and passes through the through hole on the door and window hinge link to realize the positioning of the door and window hinge link. This ensures that the door and window hinge link will not shift when drilling the door and window hinge link, and ensures the accuracy of the drilling position.

[0049] For example, in one embodiment, the drilling unit described above includes two drill bits rotatably mounted on the sliding support frame 703. The two drill bits correspond one-to-one with the two support platforms 712. The two drill bits are connected to a fourth motor 707 mounted on the sliding support frame 703 via a transmission component 706. The fourth motor 707 drives the two drill bits to rotate synchronously via the transmission component, thereby realizing synchronous drilling of the two door and window hinge linkages.

[0050] The drill bit described here is a slanted hole drill bit, used to machine slanted holes in door and window hinge links.

[0051] The second mounting bracket 701 is also equipped with a limiting component 705 and a photoelectric sensor to ensure the accuracy of the downward movement distance of the sliding support bracket 703. When the sliding support bracket 703 moves downward, the limiting component 705 can effectively limit its movement range to prevent excessive movement from causing excessive drilling. At the same time, the photoelectric sensor can accurately sense the position of the sliding support bracket 703. When the sliding support bracket 703 moves to the preset position, the photoelectric sensor sends a signal to control the equipment to stop moving, thereby ensuring the accuracy of the downward movement distance of the sliding support bracket 703.

[0052] Preferably, the second mounting bracket 701 is also equipped with an air blowing component 711, the air outlet of the air blowing component 711 facing the receiving platform 712, for blowing the waste generated by drilling away from the receiving platform 712, so as to facilitate the collection of waste.

[0053] Furthermore, an extension frame 708 is fixed on the sliding support frame 703, and a clamping member 710 is slidably installed on the extension frame 708. An elastic member 709 is installed between the end of the clamping member 710 away from the support platform 712 and the extension frame 708. When the clamping member 710 moves downward, it cooperates with the elastic member 709 to press against the door and window hinge link, ensuring the stability of the door and window hinge link during drilling.

[0054] The only difference between the flat hole drilling mechanism 8 and the inclined hole drilling mechanism 7 is the shape of the drill bit. Therefore, the flat hole drilling mechanism 8 will not be described in detail in this embodiment.

[0055] It should be noted that the first sliding guide 202, the second sliding guide 304, the third sliding guide 308, the fourth sliding guide 402, the fifth sliding guide 502, the sixth sliding guide 505 and the seventh sliding guide 704 mentioned above all include a guide rail and a slider that is slidably connected to the guide rail, for the purpose of achieving sliding guidance.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
